BUKHARA, Uzbekistan - Chinese President Xi Jinping toured the Uzbek city of Bukhara, which he called a "shining pearl on the ancient Silk Road" on Tuesday after arriving here for a state visit.

Xi and his wife, Peng Liyuan, accompanied by Uzbek Prime Minister Shavkat Mirziyoyev, took a detailed tour of the UNESCO World Heritage Site in central-southern Uzbekistan with great interest.

The Historic Center of Bukhara, situated on the Silk Road, is more than 2,000 years old. It is one of the best examples of well preserved Islamic cities of Central Asia with an urban fabric that has remained largely intact.

Standing on the Ark fortress of Bukhara, Mirziyoyev told Xi history of the city during its prime time on the Silk Road trade corridor.

"The kids in the city were playing with golden coins, in stead of playing with stones like kids elsewhere," the prime minister said.

Now a city culture museum, the Ark fortress, once residence of Bukhara's ancient rulers, hosts a series of antiques and relics including manual scripts of the Koran, art crafts, ancient coins and old weaponry that witnessed the stretching history of the city.

Bukhara was long an important economic and cultural center in Central Asia and served as a major center of Islamic culture for many centuries.
